[待解决问题]
mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View v, int position,
long id) {
for (int i = 0; i < mListView.getCount(); i++) {
View callLogView = mListView.getChildAt(i);
mRelativeLayout = (LinearLayout)callLogView.findViewById(R.id.myShow);
if(i == position){
if(mRelativeLayout.getVisibility() == View.GONE){
mRelativeLayout.setVisibility(View.VISIBLE);
}
else{
mRelativeLayout.setVisibility(View.GONE);
}
}else{
mRelativeLayout.setVisibility(View.GONE);
}
}
}
});
如题，代码以附上，ListView的项有2个布局，我现在想做的事是在点击一项ListView后显示出下面的布局，而其它项的ListView隐藏，但在超过 mListView.getChildCount()后会出现空指针，求解！

ListView的Adapter是你自己实现的么？
